Thanks for this!

In order to get ncurses-6.0 to build, I needed the following:

export CPPFLAGS="-P"

Thanks for script.
But I face a problem related to supported compression algorithms.

I want ZLIB, ZIP, BZIP2 in compression algorithm list.
So Is there any way to support for above compression algorithm
